Compile 32 bit dll for cuda on 64 bit MATLAB?

Hello sir

i am compiling 32 bit dll on 64 bit MATLAB using link (Build 32-bit DLL on 64-bit Windows Platform Using MSVC Toolchain - MATLAB & Simulink (mathworks.com) ) , integrating it with labview 2019 (32 bit) and its working fine. However, i want to compile 32 bit cuda dll on 64 bit MATLAB (for reference i have build the 64 bit MATLAB dll of the same code using GPU coder app of MATLAB). Can anyone guide me how i can compile 32 bit dll of the same code using GPU coder or this (Build 32-bit DLL on 64-bit Windows Platform Using MSVC Toolchain - MATLAB & Simulink (mathworks.com) ) ?

According to https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html#x86-32-bit-support to cross-compile for x32 you will need:

• Visual Studio 2019 16.x; or
• Visual Studio 2017 15.x (RTW and all updates)

and also that support is only provided for GeForce GPUs .

Could you confirm that you have VS 2019 or VS 2019, and that you are targetting a GeForce GPU ?

Sir thank you for your reply.

i have installed vs 2019 and checked the GPU environment setup using command coder.checkGpuInstall, as a result of this command, i can generate and excecute basic code. In addition i have Nvidia RTX 2060 GPU on which i am trying to compile the code. Sir it is pertinent to mention here that GPU coder is compiling the code perfectly but as a result of it i got 64 bit GPU code (.dll) file. i just want to compile it as 32 bit dll (like the method given by Build 32-bit DLL on 64-bit Windows Platform Using MSVC Toolchain - MATLAB & Simulink (mathworks.com) (as this link supports 32 bit compilation of c and c++ codes but not .cu codes)

If you go through https://www.nvidia.com/Download/index.aspx?lang=en-us

• Product type: GeForce
• Product series: GeForce RTX 20 Series
• Product: GeForce RTX 2060
• Operating System

... you will see that there are no drivers available for 32 bit Windows.

sir i am using windows 2010 (64 bit), using that i have successfully compiled 64 bit dll (via Matlab coder app) then i run .m file of this link Build 32-bit DLL on 64-bit Windows Platform Using MSVC Toolchain - MATLAB & Simulink (mathworks.com) and compiled 32 bit version of the same code and finally i integrated it with labview 32 bit.

now all i need it to compile 32 bit version of the 64 bit dll which is successfully been compiled via GPU coder app. i am hoping to find some work around using the same link Build 32-bit DLL on 64-bit Windows Platform Using MSVC Toolchain - MATLAB & Simulink (mathworks.com).
